1Notes on tests
2============================
3The semanage_access_check test in the semanage_store suite simulates a
4read-only filesystem by using DAC permissions. Consequently, these tests
5will fail if run as root, as root can override DAC permissions.

8How to add and use unit tests
9=============================
10
11We are using the CUnit unit testing framework. This framework--and the
12official documentation of the framework--may be found here:
13
14http://cunit.sourceforge.net/
15
16If you have not yet installed CUnit, first do that. (There is an RPM,
17or you can compile from source.) Once installed, follow these steps to
18add unit tests for your code:
19
201. Create a .h and .c file corresponding to the .c file you want to test.
21 For example, test_semanage_store.c provides tests of the functions in
22 semanage_store.c. Your new .h/.c files represent a suite of related
23 tests.
24
252. Write or add new tests to a suite. Tests are simply functions that
26 take the form:
27
28 void test_my_function(void)
29
30 These tests are where you will make calls to the CUnit assertions.
31
32 If you are making a new test suite, also add the suite init/cleanup
33 functions. These take the form:
34
35 int <suite_name>_test_init(void)
36 int <suite_name>_cleanup(void)
37
38 These functions will be called before and after the test functions
39 in your suite, respectively. They return 0 on success, 1 on failure.
40
413. Update libsemanage-tests.c to add your new suite and/or your new tests
42 using the DECLARE_SUITE macro in do_tests().
43
444. Update the Makefile:
45 + Make sure that the TESTSRC variable is set to the location
46 of the libsemanage source code you want to test.
47
485. Compile the libsemanage source code you will be testing, to ensure
49 the object files are available and up to date.
50
516. Run your tests. Rejoice or despair, as appropriate.
52
53
54A note on the the utilities.c: Add functions that can be commonly used
55here. For example, it is handy to have a dummy message callback
56function to silence error messages produced by libsemanage and keep
57your output pretty. To do this, include utilities.h and specify the
58callback like so:
59
60 semanage_handle_t *sh;
61 sh = semanage_handle_create();
62 sh->msg_callback = test_msg_handler;
63
64Feel free to add other such functions here as well.
